A lot more accurate than nothing at all.

Because that is the real question, isn't it?

nmea(4) works over serial lines, too.


How accurate is NMEA, on USB or serial without using a PPS signal line?

I run some very happy time servers on Sparcstation LX (50MHz) or
Sparcstation1 (85MHz).

Although I'm not using GPS I am using a 20 MHz Sparc with OpenBSD 3.9 as
my home NTP (and internal DNS) server. Works fine but took most of a day
to do the install. It crunched for hours making SSH keys.

I have a slower vax serving our entire network.
it doesn't have usb tho, thus no gps

A 200 MHz would do, me thinks.

Any of these will do.  An NTP server barely uses any ressources.

Hi!
You can do it on any old machine, is ti 200mhz or 1ghz :)
